Circles sells a system that enables its clients to attach this system to the infrastructure of their telecom companies, or to use a separate system called Circles Cloud, which is a system that connects to telecom companies around the globe. Circles works by exploiting Signaling System 7 (SS7) protocol, a protocol used to exchange information and routing phone calls among different wired and wireless telecommunications companies. It manipulates it for determining the geographic location of the targeted person’s phone. It can also intercept audio calls, and short text messages, which in case of being intercepted the two-factor authentication codes sent through SMSs can also be intercepted. The company determines the geographic location only by using the phone number, by determining the cellular cell the phone is connected to and its location.
